The performance standard for tank tightness testing established by the U.S. Environmental Protection Agency (EPA) regulation requires that the systems used to test underground storage tanks be able to detect leaks as small as 0.38 L/h (0.1 gal/h) with a probability of detection of 0.95 and a probability of false alarm of 0.05. The standard was developed to address tanks nominally 30,000 to 38,000 L (8,000 to 10,000 gal). in capacity or less, but also applies to tanks as large as 190,000 L (50,000 gal). The accuracy of detecting leaks in tanks as large as 190,000 L (50,000 gal) is not well known, and very little data from which to make an assessment are available. To meet EPA's regulatory standards for tank tightness testing of petroleum fuel tanks, volumetric leak detection systems must be able to accurately compensate for thermally induced volume changes in the stored fuel. A field study was done to investigate the magnitude of these volume changes.
